CEL Code experts please help!

I have these 2 codes when i read them, P0103 & P1108. Some background info is i am using a boxster air filter housing with a 996 manifold and MAF. Also i deleted all of my cats to open up the exhuast for the 3.6L currently in there. The car is running kind of like poop and i loove to fix this. I fel like im missing out on some of the 3.6L power even though its still way faster than my old 3.2L. Thanks guys!

Thanks! I'm thinkin above upper limit is meaning there is not enough air passing through with the Boxster filter housing to feed the 3.6L...

3.6l?

What flash do you have in your DME? Is it a 3.6L 911 flash? I recently read somewhere that the 996 air filter housing places the MAF sensor in a larger diameter tube than the 986 filter housing. Supposedly, if you use 996 software with the MAF in a 986 filter housing, it will run rich because the air velocity is greater in the 986s smaller tube. The air velocity difference causes the MAF reading to be incorrect. Don't take that to be gospel, though -- I just read it somewhere...

Unusual codes. Need more info. What year car, what year motor, which DME software? Any additional software revisions? I have never seen P1108.

Blue-S. I think you might be on par with that. I have the 3.6L X51 Flash on my DME currently. My shop is telling me the 996 housing wont fit but Todd says it will with some cutting. I think that is the reason why the car is running so weirdly and pulling lots of power.
